Global climate change and increased population caused significant depletion of freshwater especially in arid and semi-arid regions including Saudi Arabia. Saline water magnetization before irrigation may help in alleviating the adverse effects of salinity on plants. The current study aimed to examine the potential beneficial effects of water magnetization and soil amendments on growth, productivity, and survival of Calendula officinalis L. plants. Three types of water (tap water “control”, well water, and magnetized well water) and two types of soil amendments (Fe₂SO₄ and peat moss) were examined. Our results showed that irrigating C. officinalis plants with saline well water (WW) adversely affected growth and flowering as compared to tap water (TW). However, plants irrigated with magnetized water (MW) showed significant enhancement in all the studied vegetative and flowering growth parameters as compared to those irrigated with WW. Furthermore, mineral contents and survival of C. officinalis plants irrigated with MW were higher than those irrigated with TW. Irrigation with MW significantly reduced levels of NA⁺ and Cl⁻ ions in leaves of C. officinalis plants indicating the role of magnetization in alleviating harmful effects of salinity. The current study showed that water magnetization enhanced water quality and increased plant’s ability to absorb water and nutrients. Further studies are needed to examine the possibility of irrigating food crops with magnetized water.

全球气候变化和人口增加导致淡水大量消耗，特别是在包括沙特阿拉伯在内的干旱和半干旱地区。灌溉前将盐水磁化可能有助于减轻盐分对植物的不利影响。当前的研究旨在检验水磁化和土壤改良剂对金盏菊植物生长，生产力和存活的潜在有益影响。检查了三种类型的水（自来水“控制”，井水和磁化井水）和两种土壤改良剂（Fe ₂ SO ₄和泥炭藓）。我们的研究结果表明，灌溉Ç。厚朴与自来水（TW）相比，含盐井水（WW）的植物对生长和开花有不利影响。然而，与用WW灌溉相比，用磁化水（MW）灌溉的植物在所有研究的营养和开花生长参数上均表现出显着增强。此外，C的矿物质含量和存活率。MW灌溉的厚朴植物高于TW灌溉的那些。灌溉用MW显著降低NA水平⁺和Cl ^-中的叶离子Ç。厚朴表明磁化作用在减轻盐分有害作用方面发挥作用的植物。当前的研究表明，水磁化可以提高水质，并提高植物吸收水分和养分的能力。需要进一步的研究，以检查用磁化水灌溉粮食作物的可能性。
